        ①若夫日出而林霏开，云归而岩穴暝，晦明变化者，山间之朝暮也。野芳发而幽香，佳木秀而繁阴，风霜高洁，水落而石出者，山间之四时也。朝而往，暮而归，四时之景不同，而乐亦无穷也。
        ②至于负者歌于途，行者休于树，前者呼，后者应，伛偻提携，往来而不绝者，滁人游也。临溪而渔，溪深而鱼肥；酿泉为酒，泉香而酒洌；山肴野蔌，杂然而前陈者，太守宴也。宴酣之乐，非丝非竹，射者中，弈者胜，觥筹交错，起坐而喧哗者，众宾欢也。苍颜白发，颓然乎其间者，太守醉也。
        ③已而夕阳在山，人影散乱，太守归而宾客从也。树林阴翳，鸣声上下，游人去而禽鸟乐也。然而禽鸟知山林之乐，而不知人之乐；人知从太守游而乐，而不知太守之乐其乐也。醉能同其乐，醒能述以文者，太守也。太守谓谁？庐陵欧阳修也。
